SASH-FAS-TENER.

SPECIFICATION forming part of Letters Patent No. 699,223, dated May 6,1902. Application filed March 15, 1901. Serial No. 51,361. (No model.)

have invented a new and useful Sash-Fae tener,of which the following isaspecification. This invention relates to sash-fasteners,and

I0 has for its object to provide an improved device of this characterwhich is designed for mounting upon one of the side rails of awindow-sash and constructed for engagement with the adjacent portion ofthe windowframe, so as to lock the sash when elevated as well as whenclosed. It is furthermore designed to have the operating parts of thedevice effectually housed, so as to be protected against damage anddisplacement, and also to provide for an elastically-yieldable movementof the windoW-frame-engaging member, so as to insure an effectiveengagement thereof with the frame and to accommodate the device to anyirregularities in the frame.

With these and other objects inview the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without de- 5 parting from the spirit or sacrificingany of the advantages of the invention.

In the drawings, Figure 1 is an elevation of the lower right-hand cornerof a window-sash and the adjacent frame portion-with the Fig. 2 is afront elevation of the device detached from the window-sash with partsbroken away to show the interior thereof. Fig. 3 is a longitndinalsectional view taken on the line 3 3 5 of Fig. 2.

of the slidablelocking-bolt.

Like characters of referen cedesignate corresponding parts in all of thefigures of the drawings.

In carrying out the present invention there is provided an oblong box orcasing 1 to con- Fig. 4 is a detail perspective view tain the movable'parts of the fastener and having its opposite ends open, as indicatedin Figs. 2 and 3, there being suitable attaching flanges or cars 2 atthe opposite closed edges 5; of the box and provided with perforationsfor the reception of suitable fastening devices 3, whereby the casing issecured fiat against one of the side rails of a window-sash 4. Withinthe casing there is slidably mounted a locking member 5, which is in theform of a flat plate resting against the back of the box or casing anddesigned to be alternately projected through the opposite open ends ofthe casing. As shown in Fig. 2, itwill be seen that the plate is of awidth to fit loosely between the opposite edges of the casing, whichedges form guides for the member in its slidable movement; Theouter endof the member is thickenedor laterally enlarged, so as to forma head 6,that fits loosely against the front and back of the casing, and therebyprevents looseness of the locking member in the direction of thethickness thereof. In the outer extremity of the locking memberthere isprovided a socket or recess extending for the greater part of the widththereof, and in which is fixedly seated a strip of rubber 7 to form acushioned end for the locking member. At the rear end'ot the plate thereis provided a longitudinal slot-8, which is designed for the receptionof a stop and guide pin 9, that extends through correspondingperforations in the front and back of the casing, one of saidperforations being screw-threaded for en- *gagement with thescrew-threaded portion of the pin. A lateral projection 10 is providedat'the inner end of the slot and is in the form of an end marginalflange. It will be understood that the projection and the enlarged 0head are at the same side of the locking member.

For the manipulation of the sliding locking member there is provided acam-shaped tumbler 11, having an eccentricall-ydisposed opening for thereception of the pin 9, that also forms a pivot for the cam',:the latterhaving a handle or finger-piece 12 projected laterally therefrom inthe'plane thereof and extended outwardly through the rear open end IOOof the casing, so as to be in position for convenient operation, andwhereby the adjacent ends of the opposite edges of the casing form stopsto limit the opposite swings of the finger-piece. The body of the camrests against the inner side of the front of the casing and is providedwith an outer cylindrical marginal flange 13, as best shown in Figs. 2and 3, that lies in frictional engagement with the outer side of theprojection 10 upon the slidable locking member, so that when the cam isin the position shown in Fig. 2 and the locking member is at its outeror locked limit a downward movement of the finger-piece will rotate thecam upon its fixed pivot, whereby the flange 13, traveling across theouter side of the projection, will draw the locking member inwardly toits unlocked position. To force the locking member forwardly oroutwardly by the reverse movement of the cam, an elastically yieldableconnection is had between the cam and the member by means of an arcuatefollower 14, correspondingto and frictionally fitting the outerperipheral edge of the cam and lying between the latter and the enlargedhead of the looking member, said follower having a stem or pin 15projecting toward the head 6 and terminating short thereof, there beinga helical spring 16 encircling the stem or pin and having its oppositeends bearing against the adjacent side of the follower and the rear endor shoulder of the head.

From the foregoing description it will be apparent that the cam-shapedtumbler is mounted upon a fixed pivot that is carried by the casing andthere is a connection between the cam and the slidable locking memberfor moving the latter in opposite directions by a corresponding movementof the tumbler.

In thelocked position of the device,as shown in Fig. 1, the lockingmember is at its outer limit, with the rubber or yieldable outer endthereof in frictional engagement with the adjacent portion of thewindow-frame 17, thereby locking the sash against movement upwardly anddownwardly and holding the same in an elevated position. It will beunderstood that the device will lock the sash when closed in the samemanner. The purpose of the rubber strip 7 is to insure a tightfrictional engagement between the locking member and the window-frame,and thereby prevent slipping of the device, and also to accommodate themember to any irregularities in the frame.

When the finger-piece is thrown upwardly to force the locking memberoutwardly, the follower 14 is moved laterally outward by the movement ofthe cam-shaped tumbler, thereby crowding the spring against the shoulder(5, thus forming an elastically yieldable connection between the tumblerand the locking member to force the latter outwardly. This elasticallyyieldable connection permits of the finger-piece being moved to itsuppermost limit, as the spring will yield after the locking member is inengagement with the windowframe. It is essential that the tumbler bethrown to its limit in the locked position of the device, as the longestradius of the cam is then brought between the pivot thereof and thefollower, whereby the slidable member is locked, or, rather, the cam islocked, against accidental movement byinward pressure upon the lockingmember. Moreover, the locking member being elastically yieldableautomatically conforms to any irregularities in the window-frame andtogether with the rubber strip prevents damage to the woodwork of theframe.

Although the device has been shown as applied to theright-hand side of awindow-sash, it may be inverted and applied to the opposite lefthandside thereof, and the devices may also be made in lofts and rights, asmay be desired.

What is claimed is- 1. The combination with a locking member, of aneccentric adapted to withdraw the same to unlocking position, a followerin contact with said eccentric and adapted to be positivel y movedoutwardly by said eccentric, and a spring situated between the followerand the locking member and adapted to be compressed between the two onthe outward movement of said follower.

2. The combination with a locking member having a longitudinal slot, afixed guide-pin passing through said slot, an eccentric tumbler mountedupon the guide-pin and. having a finger-piece, a laterally-projectingportion formed on the locking member and adapted to be engaged by saidtumbler, a follower in contact with said tumbler and adapted to bepositively moved outwardly by said tumbler, and a spring situatedbetween the follower and the locking member and adapted to be compressedbetween the two on the outward movement of said follower.

In testimony that we claim the foregoing as our own we have heretoaflixed oursignatures in the presence of two witnesses.
